Patterns is a video test pattern generator for MacOS, developed by Avical, supporting HDR and SDR operation.
Patterns can be used with select Professional ColourSpace license levels, enabling verification of any screen parameters on any connected device.
Patterns is also color management compliant allowing for validation through the entire processing path.
Patterns operates in full float, or 32-bits per component, ensuring a high level of precision. As the signal travels through the system full float becomes half float, or 16-bit.
Fully compatible with select professional ColourSpace licenses, Patterns may also be used via the included web interface allowing manually entry of RGB Triplets for patch generation.
Avical Patterns operation and function is controlled via the Hardware Options menu, accessed via the Profiling window.
- Open a ColourSpace Profiling window, select Hardware Options, and select Avical Patterns from the Hardware drop-down list
- Using the Network Address window enter the required IP address, and select Connect
- Using Calibration Patches select the desired patch option to use for profiling
(Custom patch settings are defined via the Patterns Options window - Automatic uses the patch settings defined within the ColourSpace Settings window, or else the closest available patch settings)
As soon as a Calibration Patches selection is made, the output of Patterns will display the patch colour as defined within the ColourSpace Measure and Characterisation menus, as well as using the Bit Depth Resolution as set within Settings.
To use Patterns as a Patch Generator with ColourSpace navigate to the desired profiling mode - Manual Measure or Display Characterisation.
The output of Patterns will mimic the colour displayed, using the patch settings defined via Hardware Options.
Profiling can then be performed as normal, using the probe connected to ColourSpace, with Patterns displaying the required patches on the display being profiled.
